Dynamically tunable plasmonically induced transparency by planar hybrid metamaterial

Abstract

We design and numerically analyze a dynamically tunable, plasmonically induced transparency (PIT) planar hybrid metamaterial (MM) in a near-infrared regime, which combines the near-field coupling effect into dynamic MM. The embedded position of tunable material in dynamic MM is optimized. Thermal-tunable ${\mathrm{VO}}_2$ stripes are filled in the cut-out slots as components of a plasmonic system, which dramatically improve the dynamic modulation depth of the PIT. We also present a four-level plasmonic system to quantitatively analyze the dynamically tunable PIT device. This work may offer a further step in the design of the tunable PIT effect.
